Kubernetes Redis Template

Terraform module which deploys containerized Redis on Kubernetes, powered by Bitnami Charts/Redis.

• Support standalone(one read-write instance) and replication(one read-write instance and multiple read-only instances, for read write splitting).

Usage

module "redis" {
  source = "..."

  infrastructure = {
    namespace = "default"
  }

  architecture   = "replication"
  engine_version = "7.0"         # https://hub.docker.com/r/bitnami/redis/tags
}

Examples

• Replication
• Standalone
